THIMBLE.

Specification of Letters Patent.

Patented J une 25, 1918.

Application filed July 10, 1917. Serial No. 179,745.

To all whom it may concern Be it known that I, SOPHIA CoLnUnN, a citizenof the United States, residing at Fort lVorth, in the county of Tarrantand State of Texas, have invented new and use ful Improvements inThimbles, of which the following is a specification.

This invention relates to thimbles and comprehends especially theprovision of a thimble having a thread cutting attachment.

Another object of the invention is to provide a thimble of commonconstruction hav ing an opening in one side thereof near the mouth ofthe thimble in which is secured the shank of a cutting blade.

The invention also aims to generally improve combined thimbles andthread cutters to render them more practical, useful and commerciallydesirable.

With these and other objects in view as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction, combination and arrangement of parts as will behereinafter fully described, illustrated and claimed.

In the drawings,

Figure 1 is a side elevation of my combined thimble and thread cutter.

Fig. 2 is a top plan view of the article.

Fig. 3 is a longitudinal sectional view through the cutting member andthimble.

Fig. 4 is a horizontal sectional view on the plane of line 4.4t of Fig.3, and

Fig. 5 is a perspective view of the cutting element.

Referring in detail to the drawings by numerals, 1 designates a thimbleof common construction having secured thereto my improved thread cutter2 which comprises a cutting blade preferably of blue steel having itssides beveled to form an inner cutting edge 3 opposed to the body of thethimble. The free end of the cutting blade is rounded as at 4 and theother end is formed integrally With a shank 5 extending at right anglesthereto through an opening 6 in the body of the thimble. The shank isenlarged at its inner end. to form a head 7, which bears against theinner side of the thimble body and which has its outer faces curved incon formity with the curvature of the thimble. The opening 6 issurrounded with an outwardly projecting flange 8 which closely on gagesthe shank of the cutting blade, thereby reinforcing the securenlent ofthe cutter to the thimble. The close engagement of the shank 5 with thewalls of the opening 6, of the head 7 with the inner face of the thimble, and of the flanges S with the shank of the thimble may be dependedupon to hold the cutter in position but if a more rigid attachment isdesired soldering may be resorted to.

The cutter when secured to the thimble adjacent the open end thereof asshown is in a convenient position for use and the cutting edge which isspaced a slight distance from the exterior surface of the thimble is ina measure guarded so as not to injure the user and may be quicklyengaged with a thread to sever the same.

From the foregoing description taken in connection with the accompanyingdrawings, it will be apparent that I have provided a very practical,useful and much needed combination article which is superior to those ofsimilar nature used heretofore.

While I have shown and described the preferred embodiments of myinvention it will be clearly understood that I do not wish to be limitedto this construction but may make such changes as will fall within thescope and spirit of the invention as claimed.

WVhat I claim is:

The combination with a thimble having an opening in its side wall and acutting member having a shank, of flanges on each side of said openingand a head on the shank having curved faces engaging with the inner Wallof the thimble, said shank engaging said flanges.

In testimony whereof I affix my signature.

SOPHIA COLBURN.
